What is standard hydrogen electrode?
उत्तर
Standard Hydrogen electrode:
It is a reference electrode used to measure the electrode potentials of the electrodes.
In this hydrogen gas at 1 atm. the pressure is passed into HCl at 25°C in which a Pt foil coated with finely divided platinum black remains immersed. The electrode potential of SHE is taken as zero at 298 K.
